X9-4

Photometer and Radiometer for Narrow Beam and Fiber Light Sources

The X9₄ (Xnine four) meter is a compact lightweight photometer and radiometer for the measurement of luminous flux in Lumen (lm) and radiant power in watts (W) with its ISD-5-VL-4* luminous power and SD-5-VISNIR-4** radiant power integrating sphere detectors.

Lumen power measurement of cold light sources (e.g. endoscopes) employing light guides or rigid optics.

The ISD-5-VL-4 luminous flux detector is set-up with a compact 50mm diameter integrating sphere with 12.5mm measurement port. The photodiode detector with precise V(λ) photometric correction filter matches the DIN CIE standard to equal or better than 5% for DIN Class B specification.

Radiant Power measurement of light sources employing light guides or rigid optics.

The ISD-5-VISNIR-4 integrating sphere detector includes a compact 50mm diameter integrating sphere with 12.5mm measurement port and a photodiode detector with radiometric correction filter for the wavelength range from 400 to 1000nm.

Simple to Use Lightmeter

The X9₄ meter is a handheld battery operated meter with 9 mm high character LCD display for easy viewing. Its high linear current to voltage amplifier offers seven automatically (or manually?) selected gain ranges. The maximum uncertainty within this wide dynamic range is 0.2 %. Operating the X94 is simple. Once set-up all settings are stored and recalled on next power-up unless changed. The meter is operated by a standard 9V battery. An optional BHO-01 hard-shell case is available.

Traceable Calibration

Both detectors and the meter are traceable calibrated to international standards.
